| * Check if a dt node should be or was bound before relocation. |

| * - u-boot,dm-pre-reloc: legacy and indicates any of TPL or SPL |
| * Existing platforms only use it to indicate nodes needee in |
| * SPL. Should probably be replaced by u-boot,dm-spl for |
| * existing platforms. |
| * @blob: devicetree |
| * @offset: node offset |

| * Returns true if node is needed in SPL/TL, false otherwise. |
